Don’t watch this if you have a fear of heights or a fear of falling from the upper deck at a sports stadium.

A fan at the Red Sox-Mariners game on Friday night was trying to catch a foul ball, but he missed, and as he missed, he tumbled down a few rows of seats in the upper deck. Fortunately, he wasn’t injured.

Holy crap… dude falls two rows after reaching for a foul ball in Fenway.
